adrenal fatigue, vitamin C, and Heavy Metals

DR. Lamm 1. I am in advance adrenal fatigue stage 3-4, and worked with the vit C protocol, and did excellent on 3500mg in morning and 3500mg afternoon. I switched to C support, pandrenal, liponanoC, and Quantum, and it has been 20days, of continuous taking the supplements 2 days, feeling bad and stopping for 48 hours. I had 2 crashes since I stopped the 3500/3500 protocol. Do I switch to 3500/3500 of higher protocol to build my adrenals? my body cant take any of these supplements because it reacts, and I am so weak that I cant't afford to experiment what helps and what does not. 2. My saliva tests showed very low DHEA, and low testosterone and Cortzol. MY urine and hair, showed a lot of mercury and little arsenic. A. Is it better to take DHEA, or something to treat the effect of the hormones, until I get the mercury out? B. Isn't it better for me to do the IV chelation instead of building my adrenals, because of how I reacted to these Vitamin C products? Thanks
